自由标记。我将 Java 类对象作为模型传递并将其绑定到“doc”。在模板中，他们尝试调用任何方法，即使是最简单的 .toString()，我总是得到一个 NonMethodException

fr.opensagres.xdocreport.core.XDocReportException: freemarker.core.NonMethodException: For "...(...)" callee: 需要一个方法，但这已经评估为一个序列+哈希（包装器：fedom.NodeListModel）： ==> doc.toString

来自模板的示例调用：

${doc.toString()}

如何从传递的java对象作为模型调用模板中的java方法？

用户服务测试类

package ru. ... .test;
...

@RunWith(SpringJUnit4ClassRunner.class)
public class UserServiceTest {

    @Autowired
    UserServices userService;

    @Test
    public void simpleTest {
      ... 
    }

}

用户服务类

package ru. ... .services;

...

@Service
@Transactional
public class UserServices {

    @Autowired
    private DSLContext dsl;
    ...
}

因此，项目中没有配置

package ru. ...;

...

@SpringBootApplication
public class Application {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
...
}

我在 DataGridTextColumn 中垂直对齐文本

<DataGridTextColumn Binding="{Binding Path=Name}"
                    Header="..."
                    SortDirection="Ascending">
    <DataGridTextColumn.CellStyle>
        <Style>
            <Setter Property="FrameworkElement.VerticalAlignment" Value="Center"/>
        </Style>
    </DataGridTextColumn.CellStyle>
</DataGridTextColumn>

结果，单元格边框也迁移到了中间 在此处输入图像描述 ，如何才能让单元格边框不在单元格的中心绘制呢？

OdbcCommand command = new OdbcCommand(string.Format("select * from TABLE where ID_PAR = '{0}'", Id), Connection.GetConnection(database));
OdbcDataAdapter adapter = new OdbcDataAdapter(command);
OdbcCommandBuilder commandBuilder = new OdbcCommandBuilder(adapter);
adapter.UpdateCommand = commandBuilder.GetUpdateCommand();

如何仅在 ID_PAR 上使用 WHERE 条件使 commandBuilder 返回命令

UPDATE TABLE SET COLUMN_1 = ?, COLUMN_2 = ? WHERE ID_PAR = ?

当前返回这样的命令

UPDATE TABLE SET COLUMN_1 = ?, COLUMN_2 = ? WHERE ((ID_PAR = ?) AND (COLUMN_1 = ?) AND (COLUMN_2 = ?))

我将我的属性添加到控件中，以便可以通过 xaml 设置它

public class CheckBoxDataGridControl : DisabledRowsDataGrid
{
    public string ActionCheckBoxColumnFieldName
    {
        get
        {
            return (string)GetValue(ActionCheckBoxColumnFieldNameProperty);
        }
        set
        {
            SetValue(ActionCheckBoxColumnFieldNameProperty, value);
        }
    }


    public static readonly DependencyProperty ActionCheckBoxColumnFieldNameProperty;

    static CheckBoxDataGridControl()
    {
        ActionCheckBoxColumnFieldNameProperty = DependencyProperty.Register("ActionCheckBoxColumnFieldName", typeof(string), typeof(CheckBoxDataGridControl));
    }

    public CheckBoxDataGridControl()
    {
        ...
        if (string.IsNullOrWhiteSpace(ActionCheckBoxColumnFieldName))
            ActionCheckBoxColumnFieldName = "IsAction";
        ...
    }

在构造函数中，该属性始终为空。如何将 xaml 标记中的内容传递给控件的构造函数？

在某些带有 AccessViolationException 的机器上使用 AxAcroPDF 打开表单时崩溃，而在其他机器上则可以正常工作。操作系统 Windows 7，框架 4.0。应用程序 - Winforms。值得 AcrobatReader XI

很明显，当使用 AxAcroPDF 打开表单时，某些内容没有足够的权限，但我什至不知道从什么开始

Stacktrace：（可以看出是落在了组件的初始化上）

尝试删除 WebSphere 上的其他 JVM 属性

server = AdminConfig.getid('/Cell:' + AdminControl.getCell() + '/Node:' + AdminControl.getNode() + '/Server:server1/')
jvm = AdminConfig.list('JavaVirtualMachine', server)
props = AdminConfig.showAttribute(jvm, 'systemProperties').splitlines()
for prop in props:
 if AdminConfig.showAttribute(prop, 'name') == 'HttpSessionIdReuse': 
   AdminConfig.remove(prop)
AdminConfig.save()

抛出 WASX7017E：执行文件“C:\data\command.py”时发生异常；异常信息：com.ibm.ws.scripting.ScriptingException：WASX7077E：不完整的配置 ID：在“[com.ibm.security.jgss.debug(cells/BASTIONNode01Cell/nodes/BASTIONNode01/servers/server1|server.xml#Property_1) com.ibm.security.krb5.Krb5Debug(cells/BASTIONNode01Cell/nodes/BASTIONNode01/servers/server1|server.xml#Property_2) HttpSessionIdReuse(cells/BASTIONNode01Cell/nodes/BASTIONNode01/servers/server1|server.xml#Property_152805222) HttpSessionIdReuse(单元格/BASTIONNode01Cell/nodes/BASTIONNode01/servers/server1|server.xml#Property_1524058949911)]" 缺少右括号
